Gas absorption by single charged drops during their formation in a uniform electric field

Abstract

A new technique for measuring gas absorption rates during the formation of liquid drops was devised. By the technique, the amount of carbon dioxide absorbed during the formation of single charged drops was measured in the presence of a uniform electric field. Also the relationships between the surface area of the drop, its volume, and the time for one cycle of the growth of the drop were obtained using a TV system. The mass transfer rates are discussed by taking account of the surface area of the drop being formed in the electric field. It is clarified that the mechanism of gas absorption during drop formation is explained satisfactorily by the surface-stretch penetration model of Angelo et al., not only for uncharged drops but also for charged drops formed in the electric field.
